Description:
Good — here is the revised **Starling integration fixed-price spec**, tightened and now explicitly referencing: * Your defined internal interfaces / APIs * GitHub workflow * Your stack and architecture constraints You can repost this exactly. --- # Fixed Price Project – Starling Bank Business API Integration (PHP) ## ⚠️ Fixed Price Only This is a clearly scoped integration project. Provide: * Total fixed price * Delivery timeline (weeks) * Milestone breakdown No hourly proposals. --- # Project Overview We operate a UK CIS payroll platform (PayCIS) built in: * PHP 8+ * MySQL (relational, indexed) * Object-Oriented architecture * MVC-style request framework * Strict naming conventions * TLS-only environment * Subdomain-based routing * Role-based permissions The system already: * Calculates subcontractor net payments (CIS + VAT handled) * Stores validated bank details * Generates structured bulk payment lists * Manages payment lifecycle: * For Approval * To Be Paid * Paid * Maintains full audit logging * Uses defined internal service classes for payments We now require **direct integration with Starling Bank Business API**. --- # Important Architecture Note We already have: * A cleanly defined internal payment interface * Clear service-layer APIs for retrieving payable batches * Structured payment models * Consistent database schema The integration must plug into our existing payment service layer — **not bypass it or rewrite core logic.** This is an API integration project, not a system redesign. --- # Scope of Work ## 1️⃣ Starling API Client Build a reusable, clean OOP Starling client: * OAuth authentication * Secure token storage * Automatic refresh handling * Sandbox + live configuration * No hardcoded credentials * Environment-driven config Deliverable: * `starling_api.class.php` (or equivalent clean service class) * Fully documented --- ## 2️⃣ Bulk Payment Submission Using our existing internal API: * Fetch payments marked “To Be Paid” * Submit via Starling Faster Payments API * Use idempotency keys * One batch or controlled sequential processing Each payment includes: * Recipient name * Account number * Sort code * Amount (2 decimal precision) * Unique internal reference Deliverable: * Method to send payment batch * Clean separation between: * Data retrieval * API payload generation * Submission logic --- ## 3️⃣ Payment Status Handling System must: Store per-payment: * Starling transaction ID * Status (pending / completed / failed) * Failure reason * Timestamp Update internal status accordingly. Database changes allowed if necessary, but must follow our schema conventions. --- ## 4️⃣ Webhook Handling (If Supported) * Implement secure webhook endpoint * Signature verification * Map webhook status → internal payment state * Log raw webhook payload Deliverable: * Controller endpoint * Webhook log table * Replay-safe handling --- ## 5️⃣ Minimal Admin UI Additions Add to existing admin interface: * “Send to Starling” action * Starling reference display * Live payment status display * Error feedback No UI redesign required. --- ## 6️⃣ Logging Requirements Create structured logs for: * API requests * API responses * Webhooks * Failures * Initiating user Logs must include: * Payload * Response * Timestamp * Account ID * User ID Must follow existing audit log conventions. --- # Development Standards You must adhere to: * OOP principles * DRY * No deprecated PHP * No inline SQL * Clean separation of concerns * Strict naming conventions * Existing schema standards All code must: * Be production ready * Include basic inline documentation * Pass linting * Follow consistent formatting --- # GitHub Requirement All development must be: * Submitted via GitHub * Branch-based workflow * Pull request for review * No direct server edits * No ZIP file delivery Commit history must be clean and logical. --- # Security Requirements * TLS only * Encrypted token storage * Idempotency protection * No double-pay risk * Strict input validation * No credentials in frontend * Webhook verification mandatory --- # Out of Scope * Multi-bank support * Open Banking aggregation * Refund flows * International payments * Credit card processing * Accounting integrations Starling Business API only. --- # Deliverables * Working Starling sandbox integration * Production-ready live configuration * Updated schema script (if required) * Clean Starling API service class * Webhook controller * Updated admin UI integration * Deployment instructions * GitHub PR submission Proposal Must Include 1. Fixed total price 2. Timeline (weeks) 3. Confirmation of: Starling API experience OAuth implementation Webhook handling Fintech or banking integrations Examples of similar API integrations
